Abstract

Profile segments of a vulcanizing mold each contain a basic body which has a profiled forming area on an inner side. A multiplicity of bimaterial rods that are aligned parallel to one another are arranged in each profile segment pressing die such that the longitudinal axes of the bimaterial rods are aligned approximately perpendicular to the forming area surface. The bimaterial rods each contain a core of a filling material disposed parallel to a longitudinal axis. A layer surrounding the core is parallel to the longitudinal axis and is formed of loosely bound-together metal powder, and that, to obtain a green profile segment part, the bimaterial rods are pressed in the pressing die and that the green part is subsequently subjected to a sintering process, by which the filling material can be removed, so that micro channels, that are arranged approximately perpendicular to the forming area remain.
